![]() Refraction Glossiness simulates a rougher surface, by diffusing the light rays in different directions. If you adjust both of these parameters (Fog Multiplier and Fog Bias), you should be able to achieve any effect you might need. Lower values make the color more intense and the transitions sharper, while higher values make the tinting more weak but even. Use Fog Bias to control the color transitions. Larger objects will look darker than smaller ones when using the same material. It works realistically, since thicker parts of the model will be more colored/darker than the thin parts.ĭepending on your object’s physical size, you might need to adjust the Fog Multiplier Value. So, how do we actually get colored refractions, if it’s not recommended to use colors in the Refraction amount? We should use the Fog color option, in this case. If you are not using Caustics in your scene (most likely you aren’t), turn on the “Affect Shadows” option to get realistic, transparent shadows. It can be grayscale or colored, but it is recommended to stick to grayscale for more realistic results. ![]() The amount of Refraction can be controlled by a number, Map, or Texture. Some typical examples that use this V-Ray material component are: glass, water, transparent plastic, crystal, oil, etc. For example, if you were to shine a light on an object, how much light would you see coming through the other side? Unlike Reflection, not all objects are refractive. Refraction controls how an object lets light through. This week, we’ll be moving on to: Refraction Last week, we talked about the Reflection tab. The information covered here is generally useful in V-Ray for C4D, but the specific fields and values may be different. While the example images are from 3ds Max, the same concepts and settings can be used in V-Ray for Maya. ![]() We’ll cover the theory behind many of the features of the material and give you specific examples of settings and tricks to use. In this series of Turbo Tips, we’re giving you an in-depth guide to regular V-Ray Material.
